[AOS12-P01] Impact of the nutrient transport through the Tsushima Strait on the ecosystem in the Japan Sea
Keywords:Tsushima Warm Current, nutrient transport, the Sea of Japan
The recently studies indicated the contribution ratio in the nutrient transports on the sources from the Kuroshio and the rivers also change, when the yearly nutrient transport changes (e.g. Morimoto et al., 2012).
We developed a coupled ocean circulation and ecosystem model, in which the lateral boundary condition is applied based on observation data, and investigated the biogeochemical responses in the Japan Sea and the East China Sea to the interannual variations in the nutrient flux through the Tsushima Strait. We discussed about the contribution ratio in the nutrient flux on the 6 sources from Kuroshio, Taiwan Strait, Changjiang river, Yellow river, the dust, and the bottom (Yellow Sea).
